Menglei Chai, Changxi Zheng and Kun Zhou Reduced hair models have proven successful for interactively simulating a full head of hair strands, building upon a fundamental assumption that only a small set of guide hairs are needed for explicit simulation, … Continue reading →

Yunfei Bai, Danny M. Kaufman, C.Karen Liu, Jovan Popović Animation artists enjoy the benefits of simulation but do not want to be held back by its constraints. Artist-directed dynamics seeks to resolve this need with a unified method that combines … Continue reading →

Fang Da, David Hahn, Christopher Batty, Chris Wojtan, Eitan Grinspun We propose a novel surface-only technique for simulating incompressible, inviscid and uniform-density liquids with surface tension in three dimensions. The liquid surface is captured by a triangle mesh on which … Continue reading →

Gergely Klar, Theodore Gast, Andre Pradhana, Chuyuan Fu, Craig Schroeder, Chenfanfu Jiang, Joseph Teran We simulate sand dynamics using an elastoplastic, continuum assumption. We demonstrate that the Drucker-Prager plastic flow model combined with a Hencky-strain-based hyperelasticity accurately recreates a wide … Continue reading →

Xinxin Zhang, Minchen Li, Robert Bridson Most fluid scenarios in graphics have a high Reynolds number, where viscosity is dominated by inertial effects, thus most solvers drop viscosity altogether: numerical damping from coarse grids is generally stronger than physical viscosity … Continue reading →

Gilbert Bernstein, Chinmayee Shah, Crystal Lemire, Zachery DeVito, Matthew Fisher, Philip Levis, Pat Hanrahan Designing programming environments for physical simulation is challenging because simulations rely on diverse algorithms and geometric domains. These challenges are compounded when we try to run … Continue reading →

Marcos Sandim, Douglas Cedrim, Luis Gustavo Nonato, Paulo Pagliosa, and Afonso Paiva This paper presents a novel method to detect free-surfaces on particle-based volume representation. In contrast to most particle-based free-surface detection methods, which perform the surface identification based on … Continue reading →

Yu-Hong Yeung, Jessica Crouch, Alex Pothen We present a finite element solution method that is well-suited for interactive simulations of cutting meshes in the regime of linear elastic models. Our approach features fast updates to the solution of the stiffness system … Continue reading →

Fredrik Kjolstad, Shoaib Kamil Jonathan Ragan-Kelley, David I.W. Levin,Shinjiro Sueda, Desai Chen, Etienne Vouga, Danny M. Kaufman, Gurtej Kanwar,Wojciech Matusik, and Saman Amarasinghe Using existing programming tools, writing high-performance simulation code is labor intensive and requires sacrificing readability and portability. … Continue reading →
